Nondestructive moisture meters are now widely used in determining moisture levels in concrete, gypsum and other floor slabs. A new ASTM International standard qualifies the types of meters suitable for this purpose and provides guidelines for how, where and when such moisture meters are used and what limitations exist.

he new standard, F2659, Guide for Preliminary Evaluation of Comparative Moisture Condition of Concrete, Gypsum Cement and Other Floor Slabs and Screeds Using a Nondestructive Electronic Moisture Meter, was developed by Subcommittee F06.40 on Practices, part of ASTM International Committee F06 on Resilient Floor Coverings.

"F2659 is very useful as a fast and easy preliminary standard because the user can take multiple tests and get instant readings across the slab in a short time," says Sean Fallon, an F06.40 member. Fallon notes that the new standard can be used by anyone who needs to be concerned with the moisture condition of a floor slab, including flooring installers, consultants and inspectors, and material manufacturers and suppliers.

The subcommittee invites all interested parties to participate in the further development of F2659.
